Abstract:It is difficult to detect the common defects of copper tubular billets online, which include holes, inclusions, cracks, uneven wall thickness, etc. Ultrasonic non-destructive testing technology was introduced and an ultrasonic online inspection system applied to the melting and casting site was designed and developed. Combined with the actual demand on flaw detection in the horizontal continuous casting process of copper billets, it is designed to use multiple groups of volume defect, line defect and geometric defect detection probes, which can simultaneously realize online detection of holes, cracks and wall thickness uniformity. A database management system has been developed for the detected copper tubular billet defect data and real-time process parameter data of horizontal continuous casting, which realizes the integration, summary and preliminary analysis of various data in the horizontal continuous casting process, and provides an information-based and intelligent database management tool for the establishment of the relationship between defects and process parameters.
